I have two urinals with waltec manual flush valves that are side by side. One of them runs all the time very slowly and won't flush manually. The other flushes manually but with very low pressure.
Any troublshooting advice would be helpful.
Thanks

Waltec flush valve t2 model is always running , should I just replace it with a new cartridge. Where is the cartridge area is , is it where the handle area is .
